Amber Frey Tells Her Story

Amber Frey says sometimes, she still thinks about Scott Peterson - the man who romanced her and then sparked suspicions and fears when she found out he was married and his wife was pregnant and missing.

Frey went to the police and at their request tried to trick Peterson into making incriminating statements. But she reportedly rejected lucrative offers for interviews and the like during the trial, at which Peterson was convicted and sentenced to death for murdering his wife, Laci, and their unborn son.

Frey is speaking more freely about her story now - making the rounds on interview and talk shows to promote her book, "Witness For the Prosecution of Scott Peterson."

The book, which very few people have seen, is already ranked 20 on Amazon.com even though its official publication date isn't until Tuesday.

In the book, Frey says she can't help wondering whether there are times when Peterson thinks about her.

Bits of the book became public earlier than planned when some of the volumes were mistakenly stocked and sold in Peterson's hometown, Modesto, Calif., over the weekend - several days before the publication date.

Before the books were removed from shelves Saturday, the local paper obtained a copy.

According to the Modesto Bee, the 214-page book, published by Regan Books, has chapter titles such as "Oh My God! Laci's baby is due on my birthday!" and "Isn't that a little twisted, Scott?"

Excerpts of the book also are in this week's issue of People magazine.

"She felt justice had been served," said People senior writer Michele Green on CBS News' The Early Show. "I think by then she was so far distanced from the Scott Peterson that wooed her and she had fallen in love with. She felt vindicated and felt glad she had come forward and taken that very difficult step."

Frey also writes that she was afraid during the murder investigation, in which she played a key role by allowing police to tape her telephone calls with Scott Peterson.

Frey testified for six days in his six-month-long murder trial, during which prosecutors played hours of the taped calls. Though Peterson never implicated himself in the calls, they were central to the prosecution's case against him, portraying him as a callous liar who continued to carry on his affair even as police searched for his wife.

Peterson first told Frey he was unmarried, then claimed he had been married once but "lost" his wife. About two weeks later on Christmas Eve 2002, the 27-year-old Laci Peterson disappeared.

Her remains and those of her 8-month-old fetus were discovered in April 2003 along the San Francisco Bay shoreline, not far from the spot where Peterson claims to have been fishing on the day Laci was last seen alive.

While the judge is expected, at the formal sentencing on Feb. 25, to accept the jury's recommendation of a death sentence, Peterson's legal team has not given up and plans to appeal the verdict.

Defense attorney Mark Geragos has also allowed part of his law firm's web site to be used for a statement that proclaims that Peterson is not guilty. The statement also appeals to the public for donations "to continue to investigate the murders of Laci and Conner Peterson so that we can free the man we know is innocent."
